Ah, I was about to drop ano natsu, but I decided to stay until 2nd episode. Looks like I'm watching all the way lol

Okay Bowei, I edited the OP for Project H so it's a bit more concise and makes more sense to me... I also added some 3D renders in there as well. It's been bothering me for some time, but I just now had time and felt like editing it...

Summary of Project H:

Inside Project-H is an Objective 2 amplifier with a Burr Brown 2134 op amp and dual NJM4556 recommended high output buffer performance opamps to drive even the most power hungry planar magnetics. The DAC is the Cirrus Logic CS4398, which has been highly recommended by Kiteki for being more natural and is also used in the Marantz CD6003 player, ($500 USD) Decware ZDAC 1, ($875 USD) and also the Esoteric X-05 SACD player ($5000 USD, yes that is the right number of zeros). There is also a control board which manages power for the DAC and O2, as well as receives the line out from the DAC and line in from the O2. The control board will have two different states, one will have the line out from the DAC go directly to the O2, while the other state will send the DAC out and O2 line in to RCA jacks on the back, allowing you to hook up another DAC to the O2, or a different amp to the DAC. The front of the case will have a 1/4" headphone out. The case as of right now seems to be made out of aluminum, with 3mm front and back panels, and completely black 

 


 

Why Project H?:

 

Options: It not only features some of the most coveted non snake oil parts around such as a full Objective 2 and CS4398 DAC but also has a central command board to relay switch signals and combine and separate the units. This is done with a fully customized design from the engineer of the project, Borisu.

 

Feel: With such a decision on getting these black gloss cases, one can get the look and feel of a much more expensive unit at such a low price. The case features a 3mm front bezel made of solid aluminium. The case comes in at 26 cm X 15 cm X 7 cm. 

 

Cost: An O2 would cost $170-$200($150 base+$15 adapter and $15 shipping) after shipping and wall adapter from most companies. And those utilize batteries. Batteries do have their pros, such as being able to move the O2 around your house easier, but also leads to lower power output. We did not strive for just an O2. We strived for more, we strived to make a Objective Desktop Amplifier using the O2. This is not the portable O2 anymore, this is a full desktop vartiant. Fully featured dual amp and DAC switching units are rare if non existent for most around. 

 

Projected unit cost FOR U.S/CANADIAN people:

$130-$140 for unit itself

~$15 wall wart

~$30 shipping

 

Broken down

~$85 Main components and accessories:

Front panel switches and buttonsand RCA on back

Objective 2 Amplifier PCB and components (includes some custom components as well such as 1/4" headphone out and BB op amp and wiring to DAC)

Cirrus Logic CS4398 Flagship DAC 

Custom b1o designed Project-H controller PCB(to control all aspects of the case it uses a micro processor which handles power management, switches, State Switching tech and more)

Volume Pot

 

$30-$35 case (just an estimate right now)

$15 per person *gift* to Borisu (imagine how long it took to solder all the boards, design the dam custom board, fit them into the cases, glue them and finally package and ship ten 5lb units.

$15 wall wart

$30 shipping

 

Total for unit itself: $135 

 

Total is around $170-$180 completely DONE, shipped with power supply to your house.

 

This is within expectations. Sub $200 unit.

Haha I'll try not to flame. We enthusiasts all have similar interests, so I think Asian pop rock is fine too. I'm heading to bed now, see you guys tomorrow.  How do you check the subscription panel. How was the other one special?

Take it out 10X a day and you have no problems for a decade.

Oh question, do jacks wear out? I thought they could have stuff taken in n out indefinitely :s

Yeah, Borisu is a freaking DIY master, except for when he told me to remove some components off my phono pre-amp because he thought they were bad, when in reality they were fine, so I'll have to order some new ones when I order a new PSU... :/

 

Jacks wear out, just like everything else. They're relatively easy to fix though, and I wouldn't worry about it too much. I haven't had my gear too long, but I've had my O2 since Feb and I connect/disconnect stuff a few times a day and I haven't had a problem yet. My iPod on the other hand... The stupid piece of schiit replacement jack for that died the 10th time I plugged my B2s into it... >:(

Talk to Numbers kun through PMs here or over Facebook...

post #48787 of 151154

Ohayou~

 

what's the p-h post doing here..?

btw, I'll probably be able to get a few units out during chinese new year holiday :)

 

oh and if anyone is wondering, I'm not "building" a beta22.

it's already built by tilpo, I'm simply putting the completed boards in a case.

the deal was that I have to sell it afterwards and give him back the larger share of the profit.

Ah, alright! Is numbers even active here? I don't think I've seen him here...

Because Bowei repeated a LOT of things, had some incorrect grammar, ect. So I fixed it since it was bothering me.

Can mine be one of the first because I was the CAD designer? Also, I still need to pay you the rest of the money for the unit ;)
I'll be skyping you tonight throwing a bunch of questions at your face about stuff. Too busy to bother right now though. I should be doing my online English homework...

I may be over exaggerating but some plugs die young others die old. P-H is a DIY unit so even if it dies, its easy solder out and replace.

 

Kinda, it takes some settings and characters from onegai teacher and some other thigns that are close to Birdy the almighty but otherwise that's about it.

 

me :)

You can send them to crucial people first that want them first. Kalbee and Jgray I think are the ones.

He's not very active. He is a smart asian at a nice school. So yeah, his last posts were on working to get Straight A's or something.

They're such a ******* pain in the god damn bitch ass to take apart and put back together that I've been procrastinating on it for about 9 months now. I even bought a red clickwheel for the next time I take it apart so it will look  badass with my blacked out case!!!

I'd buy a p-h, but when I checked by 3 weeks ago, it was full... frown.gif. I ordered a ZO2.3, but if someone has dropped out, I'd cancel the order, and get this amp. smily_headphones1.gif

Mechy wants biggrin.gif

 

I don't really need it yet. It would be nice though as a FiiO, Oblanc, RHA, Audeze , Heir audio unit are on their way !....yes. Heir Audio's will arrive in a few months but that is still fine.

 

Headamp is doing a headphone borrow right now. I applied and looks to be able to get a unit for borrowing for a few weeks :) I choose to borrow the Audeze LCD 2. U.S residents only

Damn it Bowei, you better edit that post with at least SOME of the changes I made! lol
